As Luna and Sombra were walking back to the castle when a guard came running towards them.
"Princess Luna, your sister requests your presence immediately," he said.
"I will be there straight," she replied, "Sombra head home to your father now I think something is wrong."
"Alright be safe," he said.
Luna flew as fast as she could to meet with her sister.
"Sister I came as fast as I could, what has happened?" Luna asked.
"Discord's chaos magic got out of control, he has left, but he will come back to fight us," Celestia replied.
"He must want to make everything chaotic," Luna said.
"Yes, thou art right in saying that," Celestia said.
"What are we to do?" Luna asked.
"We must use the Elements of Harmony to stop him, or he will take over all of Equestria," Celestia said.
"This must be difficult for thee, he is your husband, and Cyrus's father," Luna mentioned.
Celestia then began to break down in tears.
"Luna, this is one of the worst days of my life, my heart is breaking in two as we speak," she said, "but we must defeat him for the good of our subjects.
"I will retrieve the elements sister," Luna said, "then we will wait for him to return."
Just as Luna was leaving a blast of powerful magic broke a huge hole in the wall, causing both sisters to collapse to the ground. The ponies below consumed in fear began to panic, and run widely about Canterlot. Sombra began to run towards the castle to help Luna and Celestia, but there were too many ponies coming straight at him, trying to leave the city to reach safety. All he could hope for was that they were still alive.
"Discord show your self!" Celestia exclaimed.
"My dear Tia must you be so serious?" Discord asked.
"Where art thou coward?" Luna asked.
"Now Lulu do not be a bore like your sister," he said.
"My sister and I are right to be serious when our subjects need protection, now stop hiding at fight us coward," Luna replied.
"Oh this will be such a joy for me," he said excitedly.
Discord then blasted more magic towards them. After they avoided the blast they were now outside the castle, and they were visible to Sombra who was watching with terror at the scene.
"Luna this way hurry," Celestia said.
"Oh how adorable you think you can escape my chaos," Discord said laughing.
Discord hit Celestia and Luna with his magic, causing them to fall to the ground below them. They took that opportunity to dash inside the castle to retrieve the elements. Soon, they appeared once more, but they now had the elements. They blasted Discord and he turned to stone. Seeing the battle was finished, Sombra ran to their side.
"Luna!" Sombra yelled.
"Sombra we are here listen to my voice," she replied.
"Thank goodness thou art both alright," he said.
"Thank goodness thou art alright," Luna replied.
Celestia was crying once more, kneeling at the statue's side.
"Celestia how art thou feeling about these events?" He asked.
"I am feeling much better since we have stopped Discord from taking over Equestria, but I do still love him, and I miss him," she replied.
Eventhough all of Equestria was safe, the heartache of Celestia was painful for her loved ones to witness. The ponies all rejoiced, as she grieved. Luna on the other hand hated him because he had betrayed them for his own interests. Sombra did not know what to think, he barely knew him, so he just watched as Celestia cried, and as Luna looked upon Discord with hatred in her eyes. However, happiness then returned to Celestia because Luna was to be married to Sombra soon.
